Abstract
Ten polypyromellitimides, seventeen poly(imide esters) and six poly(im ide amides) have been synthesized. The stability of 0.5% solutions of the poly(amic acids) in DMF, and the hardness, adhesion to glass and q uality of nematic liquid crystal alignment of the polyimide layers usi ng the interference wedge method have been tested. The relationship be tween the chemical structure of polyimides and their properties, espec ially the alignment depth, is discussed.
